++ * This describes an MC68681 DUART. It has almost only overlayed registers, which
++ * the structure very ugly.
++ * Note that the ri-register isn't really a register of the duart but a kludge of bsc
++ * to make the ring indicator available.
++ *
++ * The data came from the MFC-31-Developer Kit (from Ralph Seidel,
++ * zodiac@darkness.gun.de) and the data sheet of Phillip's clone device (SCN68681)
++ * (from Richard Hirst, srh@gpt.co.uk)
